ISDN Module NM-8B-S/T and Router 2921 Compatibility

[limlayhin]

Hi All,

I am planning to do Tech Refresh on my existing Cisco 2621XM router. 

The router has NM-8B-S/T - 8 Ports ISDN BRI modules. 

The new router will be 2921.

Can I fit NM-8B-S/T from Cisco 2621XM into new Cisco 2921 router? 

Thanks all for the help.

Won't work.  

The replacement part is HWIC-4B-S/T.
